Hi guys,

I currently have the following set up:
1x Asus MB-Z87-PRO ATX Mainboard
1x Intel Core I5-4670K (3.4G, 6M Cache, HD 4600
Graphics, Overclock unlock)
2x Corsair Vengeance 1833MHz 8GB
1x Seagate 1TB SATA Hard Disk Drive
1x Kingston SSD 120GB NOW V300 SATA 2.5
1x Corsair HX1050 Power Supply
1x NZXT Phantom 410
2x ASUS R9 280X-DC2T-3GB DDR5
2x Cooler Master Sickleflow 12cm Fan
1x Cooler Master H100i Extreme Performance CPU Cooler

and I was able to pick up a MSI HD7990 for very cheap, I was wondering if my current 1050W PSU can handle it although I know I am pushing it. Thanks!

Thanks, but are you sure that you have put in 2 R280X so that I will have a total of 3 video cards(4 GPUs)? Actually I wont be able to use both 5 and 7 as the cards are pretty quick, thinking of using riser cables. Thanks.

I'm pretty sure I included all 3 video cards. I admit I hadn't tried removing one to make sure the calculator was taking it into consideration, but now I'm having trouble getting the outervision site to load at all. :( I was having similar trouble a few months ago, but I thought the problem had gone away. If the site loads for you, feel free to try it yourself and let me know what it gives you for a recommendation with and without the 7990.
